Hi,
Like old topic says : https://community.st.com/s/question/0D50X0000BbNEpXSQW/fatfs-emmc-always-frdiskerror?t=1573783271738
I`m trying to build project for STM32H743 with STM32CubeMX, and use eMMC for my storage space.
eMMC : Micron 4GB
Manager File : FATFS
This is the (Left)CSD Register it retured & (Right)the Micron datasheet
And I have no ideal about
MaxRdCurrentVddMin,
MaxRdCurrentVddMax,
MaxWrCurrentVddMin,
MaxWrCurrentVddMax, are all zero,but the true value is not.
Can anyone help?
I`ll really appreciate.

Hi, were you able to solve this? I am getting the same error when I try to use an SD card with STM32H7

Hi @Charlie CHEN
Could you try to use the Polling API instead of the DMA one to discard any potential issue related to cachee maintenance?
